Celebrating today's contract renewal, Nike has revealed the most important Mercurial boots worn by Cristiano Ronaldo since he signed for the Swoosh in 2003.

2003 - 2009

Ronaldo's first boot with Nike was the Mercurial Vapor I. He wore it to the all-important August 2003 friendly between Sporting and Manchester United. Ronaldo continued wearing the following generations of the Nike Mercurial Vapor before joining Real Madrid in 2009.

2009 - 2011

Cristiano Ronaldo enjoys a successful start to his Real Madrid stint and receives his very first signature boot, the so-called Safari edition, the year after.

2012 - 2014

In late 2012, Ronaldo received one of his more iconic signature boots. The Mercurial Vapor VIII combined black with blue, pink and white and was used to great success from the start. Several more signature editions based on the Vapor 8 and 9 followed before Ronaldo switched to the first-ever high-collared Mercurial Superfly for the 2014 World Cup.

2014 - 2016

Over the next years, Ronaldo receives numerable special editions based on the Superfly IV, before making the switch to the new Mercurial Superfly V in Summer 2016. Just a few days ago, the first signature edition based on the Nike Mercurial Superfly V was released.
